Campbell-Napier-Railton Bluebird of 1931 was rebuilt significantly. The overall layout and the simple twin deep chassis rails remained, but little else. The bodywork remained similar, with the narrow body, the tombstone radiator grille and the semi-spatted wheels, but the mechanics were new. Most significantly, a larger, heavier and considerably more powerfulRolls-Royce R V12 engine replaced the oldNapier Lion , again with supercharger.cite web

url=http://www.sirmalcolmcampbell.com/sir33.html many period photos]Bluebird's first run was back at Daytona, setting a record of 272mph on 22nd February 1933.
Campbell now had a car with all the power that he could want, but no way to use all of it. Wheelspin was a problem, losing perhaps 50mph from the top speed.
1935
Visually the car was quite different. The bodywork was now rectangular in cross section and spanned the full width over the wheels. Although actually higher, this increased width gave the impression of a much lower and sleeker car, accentuated by the long stabilising tailfin and the purposeful raised ridges over the engine camboxes.cite web

publisher=Racing Campbells]'Bluebird' made its first record runs back on
Daytona Beach in early 1935. On 7 March 1935 Campbell improved his record to 276.82 mph, but the unevenness of the beach sand still caused a loss of grip and he knew the car was capable of more.cite web

Bonneville Salt Flats ofUtah . This time the youngDonald Campbell accompanied his father. On 3rd September 1935, the 300mph barrier fell by a bare mile-per-hour, crowningSir Malcolm Campbell 's record-breaking career. cite book
